Raman Process Monitoring Probe Design Patents: Who Leads and Where the Gaps Sit
Filing has plateaued, not fallen. 2021 to 2024 filings moved from 128 to 125, a -2% shift over the complete three-year window — a mature but still-active field, not one in decline. Annual filings climbed from 80 in 2017 to a peak of 170 in 2020, then eased back. The 2021-to-2024 window — the most recent stretch that can be treated as complete — moved from 128 to 125 filings, a -2% change that reads as a plateau rather than a decline. Years after 2024 are still filling in as publications catch up to filing dates.

Common questions about this landscape
Who holds the most patents in Raman process monitoring probe design?
The leading assignee in this corpus holds 93 of the 2,225 records in scope, well ahead of the fifth-ranked company at 41. However, the top 5 assignees combined account for only 14.9% of all records, so no single company controls enough of the filing space to be treated as the sole gatekeeper. A freedom-to-operate review should look across the full 100-company ranking rather than assuming the leader's portfolio covers the field.
Is filing activity in Raman probe design growing or shrinking?
Filing peaked at 170 records in 2020 and has since settled into a plateau: the 2021-to-2024 window, the most recent stretch complete enough to read reliably, moved from 128 to 125 filings, a -2% change. That is a mature, steady field rather than one in decline. Figures for 2025 and 2026 will look lower simply because publication lags filing by roughly 18 months, so they should not be read as a downturn yet.
What IPC classes matter most for Raman probe patents?
G01N (material analysis and testing) appears on 99.6% of records because it effectively defines the search scope, but the more informative class is G01J (radiation and light measurement) at 46.3%, which reflects the centrality of optical path and light-management claims. A61B (diagnosis and surgery) and G02B (optical elements) follow at 16.7% and 12.3%. Because records can carry multiple IPC codes, these shares are not mutually exclusive and add up to more than 100%.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Raman Process Monitoring Probe Design covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
